Chrysanthemum plant named ‘Zanmulpine’

ABSTRACT

A chrysanthemum plant named ‘Zanmulpine’ characterized by its medium sized blooms with white ray florets and prolific branching; natural season flowering date October 9; blooming for a period of 5 weeks.

Botanical designation: Chrysanthemum x morifolium Ramat.

Cultivar denomination: ‘Zanmulpine’.

RELATED CULTIVARS

This new plant cultivar ‘Zanmulpine’ is of the botanical classificationChrysanthemum x morifolium Ramat.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofchrysanthemum plant, botanically known as Chrysanthemum x morifoliumRamat., commercially known as a garden mum, and hereinafter referred toby the cultivar denomination ‘Zanmulpine’. ‘Zanmulpine’ is a product ofa breeding and selection program for outdoor pot mums (garden mums)which had the objective of creating new cultivars with a double typeinflorescence, a natural season flowering date around October 9,blooming for a period of 5 weeks. ‘Zanmulpine’ is a seedling resultingfrom a cross of the female parent 36979 (unpatented) with the maleparent 37034 (unpatented). Plants of the new cultivar ‘Zanmulpine’differ from plants of the female parent in the ray-floret color,ray-florets of the seedling are white, while those of female parent showsome pink coloration due to anthocyanin formation at low temperatures.Plants of the new cultivar ‘Zanmulpine’ differ from plants of the maleparent in the following characteristics. (1) Inflorescence color. And(2) Inflorescence size. (1) Inflorescences of the seedling are morewhite than those of the male parent.(2) Inflorescences of the seedlingare larger than those of the male parents.

The new and distinct cultivar was discovered and selected as a floweringplant by Sjoukje Heimovaara on a cultivated field in Rijsenhout, TheNetherlands in October 2012. The first act of asexual production of‘Zanmulpine’ was accomplished when vegetative cuttings from the initialselection were propagated further in a controlled environment inRijsenhout, the Netherlands, in December 2012. In summer, about 6-8 daysare needed to initiate roots in cuttings of the new cultivar, afteranother 5 days rooted plants are formed. The new cultivar has been foundto retain its distinctive characteristics through successivepropagations.

BRIEF DESCRIPTION OF THE DRAWINGS

The present invention of a new and distinct variety of chrysanthemum (ofabout 20 weeks) is shown in the accompanying drawings, the color beingas nearly true as possible with color photographs of this type.

FIG. 1 shows a plant of the cultivar in full bloom.

FIG. 2 shows the various stages of bloom of the new cultivar.

FIG. 3 shows the various stages of foliage of the new cultivar.

DESCRIPTION OF THE INVENTION

The observations and measurements were gathered from plants in theperiod of 18 to 23 weeks of age grown outdoor in Rijsenhout, theNetherlands, under natural day length and temperature and planted inweek 23 in 2017, receiving drip irrigation. The natural blooming date ofthis crop was October 9 (week 41). The average height of the plants was40 cm. No growth retardants were used. No tests were done on disease orinsect resistance or susceptibility. No tests were done on cold ordrought tolerance. This new variety produces medium sized blooms withwhite ray florets blooming for a period of 5 weeks.

From the cultivars known to the inventor the most similar existingcultivar in comparison to ‘Zanmulpine’ is ‘Zanmudove’ (U.S. Plant Pat.No. 24,618). When ‘Zanmudove’ and ‘Zanmulpine’ are being compared thefollowing differences are noticed: (1). Natural season blooming date.And (2). Plant vigor. (1). Plants of ‘Zanmulpine’ flower later in theseason than plant of ‘Zanmudove’. (2). Flowering plants of ‘Zanmulpine’are larger than those of ‘Zanmudove’

The following is a description of the plant and characteristics thatdistinguish ‘Zanmulpine’ as a new and distinct variety.

The color designations are taken from the plant itself. Accordingly, anydiscrepancies between the color designations and the colors depicted inthe photographs are due to photographic tolerances.
